Is it just me or has the world gone framework crazy? Christian Montoya put together a table of some of the most popular frameworks (although some prefer to refer to them as development kits) a couple of years ago but since then a lot more of have sprung up, with more than half a dozen popping up in the last few months.

The flurry of activity in recent months has been fuelled by the increased awareness of Responsive Web Design (RWD) with nearly all the recent offerings aimed at speeding up the process of creating responsive or adaptive layouts. There also seems to have been a focus recently on typographic styling and working to a baseline grid, although this is not just a new fad, with many of the older frameworks listed below also including vertical rhythm styles.

So which framework should you use? I personally use none of them, and lots of them. If you read the descriptions of most of the frameworks, they'll tell you that the idea behind them is to use them as starting points for your own projects, ‘frameworks’ on which to build your own markup and styles. Most of them would have started out as a set of base files that the author used to start his/her projects. I had my own default HTML and CSS files to which I added stuff I used commonly before I became aware of any of these frameworks.

Over time these files have had code added to them, taken out, and had other additional files added. Most recently my HTML template has been greatly inspired by HTML5 Boilerplate, although I tend not to use the new structural elements often yet. My stylesheets are the ones that have changed the most over time, and that's still the same today. My current stylesheet is now a .less file, rather than .css, and aside from the styles I've built up over the years, includes bits and pieces from HTML5 Boilerplate, Normalize, Gridless Boilerplate, and most recently from Golden Grid System and Bootstrap by Twitter from which I poached some improved Less mixins (also grabbed some good ones the other day from Peter Wilson).

Exploring what's under the hood of a new framework often forces you to reconsider why you do things in a certain way, and whether there is a better approach, which I think is a good thing. It can sometimes be a bit of a balancing act to incorporate other people's work while still fitting in with the way you do things, but looking at the way others do things is often the best way to learn or push your own skills forward.

So does anyone have any favourites from this list or perhaps know of others I've missed out? Or perhaps, like some, you think there are too many frameworks out there now and the sheer number of them is now actually doing more harm than good.
